Product details
Overview
TLE2064ACNG4 from Texas Instruments is a quad FET-input operational amplifier with 36V supply capability, 1.1MHz gain-bandwidth product, 120μA per channel supply current, ±14.9V output swing into 10kΩ at ±15V supply, and specified high-output drive into 100Ω loads. It serves as a precision, low-power signal conditioning amplifier in analog input modules for industrial control systems.
For engineers reviewing the TLE2064ACNG4 datasheet, TLE2064ACNG4 pinout, TLE2064ACNG4 application, or TLE2064ACNG4 equivalent, this page delivers verified specifications, package mapping to PDIP-14, real-world use cases in flight control and engine management, and validated alternative options for design continuity.
Technical Context
The TLE2064ACNG4 uses JFET-input transistors with on-chip Zener trimming for offset voltage stability, enabling low input bias current (±10pA typical) and high input impedance (10¹² Ω). Its architecture supports rail-to-rail output swing limitations but not rail-to-rail input - common-mode range extends to –11V to +13V at ±15V supply.
It delivers 2.6V/µs slew rate at ±15V supply with 46° phase margin into 10kΩ//100pF, ensuring stable unity-gain operation. The device meets stringent DC precision requirements (max 4mV VIO at 25°C for 'A' grade) while maintaining µPower operation across –40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 1.1MHz - enables stable closed-loop gain up to ~100 at 10kHz for sensor signal amplification |
| Supply current per channel | 120μA (typical) - allows four-channel operation within 500μA total, suitable for battery-backed systems |
| Input offset voltage (max) | 4mV at 25°C - supports 12-bit accuracy in 5V full-scale ADC front-ends without trimming |
| Output drive capability | Specified into 100Ω - sustains >±2V swing at 20mA load, enabling direct driving of transmission lines or low-Z sensors |
| Common-mode input range | –11V to +13V at ±15V supply - accommodates bipolar industrial sensor outputs without level-shifting |
| Slew rate | 2.6V/µs at ±15V - supports <10µs settling for 10V step inputs, critical for fast analog multiplexing |
| Input bias current | ±10pA (typical) - minimizes voltage error across high-impedance source networks (>100MΩ) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad FET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE2064CDR | Same die, plastic DIP-14 package without G4 suffix; RoHS-compliant lead finish differs (matte Sn vs Pb/Sn) | Identical electrical specs; used in non-military commercial designs where Pb-free compliance is mandatory | Select when RoHS-6 compliance is required and matte tin termination is acceptable for through-hole assembly |
| TL074CP | Lower GBW (3MHz), higher supply current (1.4mA/ch), no 100Ω drive spec; JFET input but no Zener trimming | Acceptable for general-purpose AC-coupled audio or filter stages, but insufficient for precision DC-coupled engine control | Choose only for cost-sensitive, non-precision applications where 4mV VIO and µPower operation are not required |
Compared with TLE2064CDR, the TLE2064ACNG4 offers identical performance with legacy-compatible lead finish; versus TL074CP, it provides 12× lower supply current and guaranteed 100Ω drive - critical for industrial sensor buffering where power and loading margins are constrained.

FAQ
What is the maximum supply voltage rating for the TLE2064ACNG4?
The TLE2064ACNG4 has an absolute maximum supply voltage rating of ±18V (36V total), with recommended operating range of ±3.5V to ±18V. Operation beyond ±18V risks permanent damage. At ±15V supply, it delivers ±14.9V output swing into 10kΩ, confirming robust headroom for industrial ±15V systems.
Does the TLE2064ACNG4 support rail-to-rail input or output operation?
The TLE2064ACNG4 does not support rail-to-rail input - its common-mode input range is –11V to +13V at ±15V supply. Output swing reaches ±14.9V into 10kΩ, which is near-rail but not true rail-to-rail. For applications requiring input beyond ±13V, external level-shifting is necessary before the TLE2064ACNG4 input stage.
What is the input offset voltage specification for the TLE2064ACNG4 at 25°C?
The TLE2064ACNG4 is an 'A' grade device with a maximum input offset voltage of 4mV at 25°C, as confirmed in Table 4-3 and Section 5.27 of the datasheet. Typical value is 2.6mV, and the temperature coefficient is 1μV/°C - enabling predictable drift compensation in temperature-stable environments.
Can the TLE2064ACNG4 drive a 100Ω load effectively?
Yes - the TLE2064ACNG4 is explicitly specified for high-output-drive operation into 100Ω loads, unlike earlier low-power BiFET amplifiers. At ±15V supply, it maintains >±2V swing into 100Ω, supporting direct interface with transmission lines, low-Z sensors, and actuator drivers without external buffers.
What package type is used for the TLE2064ACNG4?
The TLE2064ACNG4 uses the N package: a 14-pin plastic dual in-line package (PDIP-14) with 19.3mm × 9.4mm footprint and 0.300-inch body width. This through-hole package is compatible with legacy industrial PCBs and supports wave soldering processes without thermal stress concerns.
